5x - 18 + x = 90
6x = 108
x = 18 degrees
The volume of a cube is the length of one side cubed, therefore the side length of the cube is the cubed root of the volume. Using a calculator to find the cubed root, you find that it is 0.4 meters, or answer C.
Therefore the solution is 0.4 meters; answer C.
Answer:
a) 5/-6, - 5/6
b) 7/-2, -7/2
Step-by-step explanation:
Answer:
<h2><u><em>
a²+2ab+b²-c²</em></u></h2>
Step-by-step explanation:
Solve:
(a+b+c) (a+b-c)=
(a²+ab-ac+ab+b²-bc+ac+bc-c²)=
a²+ab-ac+ab+b²-bc+ac+bc-c²=
a²+2ab+0ac+b²+0bc-c²=
a²+2ab+b²-c²
The factor is (x+6)(x+6)
So, D. x+6 is the correct answer :)
